    摘要： A light guide plate (LGP) adapted to a backlight module having a light emitting surface, a bottom surface opposite to the light emitting surface, and at least one light incident surface contacting with the light emitting surface and the bottom surface is provided. The bottom surface has a plurality of flat surfaces and a plurality of groove groups. The groove groups and the flat surfaces are arranged in an alternating fashion. Each of the groove groups has at least two grooves. Each of the grooves has a first slanted surface, a peak, and a second slanted surface intersecting with the first slanted surface at the peak. In each of the grooves, a first edge side of the first slanted surface away from the peak is at a first distance from a second edge side of the second slanted surface away from the peak.

    摘要翻译： 提供一种适于具有发光面的背光模块的导光板（LGP），与发光面相反的底面以及与发光面和底面接触的至少一个光入射面。 底表面具有多个平坦表面和多个凹槽组。 沟槽组和平坦表面以交替的方式布置。 每个凹槽组具有至少两个凹槽。 每个凹槽具有与峰顶处的第一倾斜表面相交的第一倾斜表面，峰值和第二倾斜表面。 在每个凹槽中，远离峰的第一倾斜表面的第一边缘侧离离第二倾斜表面远离峰的第二边缘侧第一距离。

    摘要： A light guide plate has a bottom surface including flat surfaces (FSs) and a plurality of prism patterns (PPs) disposed alternately with the FSs, a light emitting surface (LES) and a light incident surface (LIS). Each FS is at a first distance respectively from the LES and the first distances gradually decrease along a direction away from the LIS. Each PP has a first slanted surface (FSS) and at least a groove having a second slanted surface (SSS) and a third slanted surface (TSS). The two opposite sides of the FSS are spaced out a second distance apart. The two opposite sides of the SSS are spaced out a third distance apart. The specific value of dividing a first orthogonal projection of the second distance on an axis perpendicular to the FSs by a second orthogonal projection of the third distance on the axis is between 0.5 and 1.5.
